Jackson problem 5.4: Magnetic induction in a current-free region

Click For Summary
SUMMARY

The discussion centers on solving Jackson problem 5.4, which involves magnetic induction in a current-free region. Participants explore the use of Taylor series expansion to derive the magnetic field components, specifically focusing on the terms b0, b1, and their algebraic manipulation. The solution provided utilizes the relationship b(z) = Bz(0,z) as a key element in the analysis. A hint suggests taking the divergence to further investigate the behavior of the b_n terms.

The Attempt at a Solution


I think that is taylor series expansion, How that can be expanded right that? even b0, b1 ... is not a differential term.

The solution just use b(z) = Bz(0,z)

The solution just use b(z) = Bz(0,z)

Hint: Try taking the divergence and see what you can do with the ##b_{n}## terms algebraically.
